Interrupts
The Z86L82/85 features five different interrupts. The interrupts are maskable and
prioritized, as shown in Figure 43. The five sources are divided as follows: three
sources are claimed by Port 3 lines P33–P31and two by the counter/timers (see
Table 21). The Interrupt Mask Register, globally or individually, enables or dis-
ables the five interrupt requests.
